Carbon Dioxide Capturing Cellulosic Materials

Detailed Technology Description

The level of atmospheric CO2 has increased rapidly in the past decades, which has resulted in serious greenhouse effect. A cellulosic yarn, functionalised by amine containing molecules, has been developed to capture CO2 from the surrounding air. This project has developed cellulosic yarns with CO2 adsorbing properties by TEMPO mediated oxidation of cellulose and amine functionalisation via a grafting reaction. These yarns can be used to produce textiles and may contribute to the reduction of CO2 levels in the environment if they are used in large quantities in everyday life. This HKRITA invention is a new product fostering sustainable development of the environment.
